In amongst my courgette, tomato and pepper plants I have one "rogue" plant which has similarities but isn't a courgette and does have such big leaves. Its leaves are symmetrical ,not hairy, 7 or 8 points, come off an upright stem ( quite thick), the leaves have faint black spots or freckles. The flower is initially surrounded by a closed bell-shaped sepal, is lilac in colour, only lasts for a day and is about 3-4 centimetres in diameter.
